### Question: How do I know if I have 5-alpha-reductase deficiency and what are the symptoms?

Puberty: Patients raised as girls often appear virilisation, such as amenorrhoea, hirsuitism, deepening of the voice, descending of the testes, enlarged clitoris or microphallus, and the urethra attaching to the phallus.
